This quad-ring is supplied in AS568-450 black Buna-N (Nitrile) 70 Shore A square profile supplied with an inside diameter of 10.475 in (266.07 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 11.025 in (280.04 mm), catalogued under part number SH70450. It uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.

The compound resists hydraulic fluids, petroleum-based oils, and many alcohols. Buna-N (Nitrile) delivers low compression set under sustained load and the most widely specified general-purpose sealing elastomer. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C).

You will find this material specified across construction equipment, general industrial maintenance, and agricultural equipment.

SH70450 ships individually. Review your operating media and conditions against this specification before installation. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
